WD Red SA500 2 TB (WDS200T2R0A)

WD Red SA500 is a line of SATA SSDs designed for NAS systems, engineered with emphasis on round-the-clock operation, caching, durability, and stable performance in multi-user scenarios. The series is available in two form factors: 2.5"/7 mm and M.2 2280, allowing drives to be used both for upgrading existing NAS systems and for building new setups with various configurations. The line operates via SATA III 6 Gbps interface and offers capacities ranging from 500 GB to 4 TB depending on the model, with the maximum 4 TB capacity available in the 2.5-inch variant. In terms of speed, WD Red SA500 delivers sequential read rates up to 560 MB/s and write rates up to 530 MB/s, while random operation performance reaches 95k IOPS for reads and 85k IOPS for writes. For NAS workloads, endurance metrics are equally important: depending on capacity, durability ranges from 350 to 2500 TBW, and the declared MTTF reaches up to 2 million hours. WD Red SA500 is built on 3D NAND and optimized for tasks such as OLTP databases, photo editing, 4K/8K video editing, and rapid access to frequently used files in storage. The line operates within a temperature range of 0 to +70 °C, supports 24/7 scenarios, and is suited for those seeking a true NAS-oriented SATA SSD rather than a standard consumer drive without consideration for continuous workloads.
